Blue Sea Systems 1801 Vessel Systems Monitor VSM 422 - Manual (Page 5)

MOUNTING CONSIDERATIONS
The Vessel System Monitor has three mounting methods: surface mount,
flat panel mount, and 360 panel mount. When surface mounted using the
supplied gasket, an IP67 waterproof rating is created for the front of the unit.
Because panel mounting systems are not waterproof, the unit should not be
panel mounted in an exposed location. For all mountings, the back of the
unit is not waterproof and must be kept dry.
